` rnicrioiv DRAFT-mesme.

^ Be n known that i, WILLIAM Mlm 4a' citizen of the United States, residing in Chicago, in the county of Cook and `State oflllinois, have invented a new and useful Improvement in Friction Draft-Rigging, of

which'the following is a speciication. y.

My invention relates to friction draft rig- `ging for railway cars.

It consists, in connection with adrawftiar,l

draft yoke, spring, followersand stop members, and friction mechanism' including "a friction shell, friction shoes and wedge, in

' 2 2, 3-3 and 21- 4, respectively of 1L' Fig. 5 is a detail side view of the `we ge;

-fview, partly in horizontal section of a ton draft rigging' embodying my invention.-

providing the friction shell with external stop projections or wings adapted to engage supplemental stops to limit the movement of the friction shell' and aid in transmitting heavy blows .or'st'rains to the draft sills or car frame members to -which the -draft rigging is applied.

Inthe accompanying drawing formin a part of this specification, Figure 1 is a an Fig's. 2, 3 and 4 are lcross sections on lines Fig. 6 is a detail perspective view of one of the friction shoes; Fig. 7 is a detail-perspective view of the friction lshell; Fig. 8 is a 'detail plan view, partly in horizontal section, showing a modification and Fig.-9

a cross section on line- 9- -9 of Fig. 8, the

.parts inside the friction shell being omitted.

vIn Athe drawing, 1 .represents the draft sills or frame members of the car,2 the.front 5 the stop members having front stops'6,

rearstops? andlimiting stops 8 and-9 for the'followers 1 0, -11 toengage, 'and supplemental stops 12, 13 for engagement with' the 'longitudinally movable friction shell 14 or 'itsfexternal stop projections or wings 15.

'.TheV springs 16 and 1 7- react at fone 'end against the friction shell 14, through'the interposed preliminary compression follower or cap 18, and at the other end against the segmental friction shoes 19, which are preferably three in number aid it inside the friction shell and are expanded outwardly thereagainst by the pyramidal or three faced wedge 20 through the interposed anti-fricf tion rollers 21.

The external stop projections or wings 15 on the frictionv shell are-preferably formed integral therewith, and are preferably of a general rectangular shape,- as will be understood from Fig. 7 of the drawing. The

upright edges or faces 22 of the-wings thus serve .as guides, by engagement with the in"- nerv faces of the stop members. The friction shell 14 also has guide anges or faces 24, 25 at its front and rear ends for engagement with the draft yoke.

26 is the tie vplate securedby bolts 27 to the draft sills and upon which the draft yoke reciprocates and by which ,the draft rigging In the modification shown in Figs. 8 and is supported in position between the draft sills.

9, the supplemental stops 12 of the .friction I shell are shownv as being on vseparate piece stop members 28, andthe front stops 6 are Aalso on Iseparate piece stop members 29 from stops 7.

I claim: 1. In a friction draft rigging, the combination with a draw-bar, draft yoke, followthe stopmembers 30, which have the rear ers and stop members, having front, roar' and limiting stops for engagement'with the followers, and provided with supplemental. stops, of afriction shell-having external vprojections for engagement with said suplemental stops, a' spring, and segmental ri'ction shoes and wedge within said `friction shell, substantiall as specified.

'2. In a friction dra rigging, the combi nation with a draw-bar, -draft yoke, followA or end sill, 3 the draw-bar, 4 the draft yoke,

ers and front and rear -sto s engaging the followers, of alongitudinaly movable friction shell, externally projecting wings on said shell at the middle portion thereof, supplementaLstops for engagement with .said

wings in both pulling and buiiing, friction -shoes withinsaid frictionl shell and a spring reacting at oneV end againstsaid shell, and at the other end against said friction shoes, substantially as specified.
